Virtually all established turfgrasses are tolerant to POST-applied Methiozolin. Methiozolin ranks as one of the SAFEST herbicides among currently registered turf herbicide. Safety has been confirmed in field tests for the following:

Tolerance of over-seeded turfgrasses is variable depending on the time after seeding and the application rate. Research is on-going to determine the timing and rate of Methiozolin under over-seeding conditions.
